Beaming Your Mind to a Starship or Colony
Can we travel the stars without a body? Explore the idea of uploading your mind and transmitting it at light speed to distant starships or colonies—becoming data instead of a passenger.

The Quiet Revolution in AI Safety
When Science Fiction Becomes Engineering
Cambridge scientists created a gel that could end arthritis pain
Cambridge scientists have created a breakthrough material that can sense tiny chemical changes in the body, such as the increased acidity during an arthritis flare-up, and release drugs exactly when and where they’re needed. By mimicking cartilage while delivering medication, this smart gel could ease pain, reduce side effects, and provide continuous treatment for millions of arthritis sufferers.
Huntington’s progression slowed by experimental gene therapy
Even hearing the phrase “Huntington’s disease” will make a room suddenly somber. So the joy that accompanied a recent announcement of results of an experimental gene therapy for the deadly diseases signaled an unfamiliar sense of hope.
In a small clinical trial, brain injections of a virus that codes for a tiny segment of RNA may have prevented the formation of the rogue proteins that make Huntington’s so devastating. The early results, announced September 24 in a news release, show that over three years, the treatment slowed Huntington’s progression by up to 75 percent. While not a cure, the treatment could potentially give people living with Huntington’s disease, who might otherwise face early disability and death, the gift of many more years of life.
The surprising new particle that could finally explain dark matter
Physicists are eyeing charged gravitinos—ultra-heavy, stable particles from supergravity theory—as possible Dark Matter candidates. Unlike axions or WIMPs, these particles carry electric charge but remain undetectable due to their scarcity. With detectors like JUNO and DUNE, researchers now have a chance to spot their unique signal, a breakthrough that could link particle physics with gravity.
Video models are zero-shot learners and reasoners
View recent discussion. Abstract: The remarkable zero-shot capabilities of Large Language Models (LLMs) have propelled natural language processing from task-specific models to unified, generalist foundation models. This transformation emerged from simple primitives: large, generative models trained on web-scale data. Curiously, the same primitives apply to today’s generative video models. Could video models be on a trajectory towards general-purpose vision understanding, much like LLMs developed general-purpose language understanding? We demonstrate that Veo 3 can solve a broad variety of tasks it wasn’t explicitly trained for: segmenting objects, detecting edges, editing images, understanding physical properties, recognizing object affordances, simulating tool use, and more.
